Help with origin and age of my Keris

[Matt]

Hi,

I have had this keris for a few years. I bought it an estate sale and have always wanted to know more about where it came from. All I know about it is that the gentleman whose estate I purchased it from was stationed in the south pacific during WWII. Any help you could provide as to its possible age or origin would be great. I know that is in rough shape and has little collectable value, but I think it is a neat piece and I would enjoy knowing more about it.

Thank you,
Matt
